Cons

Dashcam doesn’t work while parked

It combines the radar detector and dashcam into a single unit so you don’t have to worry about a bunch of different accessories on your dash. While this does make the Road Scout a little bulkier than other Cobra radar detectors, it’s well worth the added functionality you get with it.

Apart from the dashcam, you’ll still get the same high-quality radar detection you should come to expect from Cobra radar detectors, including both long-range detection and improved accuracy. The Road Scout even includes pre-loaded red light camera alerts based on crowd-sourced data and your GPS location. The unit is also compatible with Cobra’s iRadar app, which enables real-time updates and speed trap tracking. You’ll also access your dashcam footage via the app. It’s not a stretch to say this is the best Cobra radar detector on the market in terms of the wealth of features it offers.

Anti-falling tech eliminates false alerts

Included mount isn’t the best

Don’t let the Cobra iRAD’s super simple and low-profile design make you overlook this excellent radar detection unit. Contrary to how it looks, this radar detector contains some of Cobra’s most advanced and cutting-edge features to date. For starters, you get long range detection for a wide variety of signals, including x, ka, and back, along with a signal strength display that gives you an estimate of how far away the source of the signal is. You also get clear voice alerts when a signal is detected so you don’t have to constantly watch the display. These voice alerts can also be muted with the touch of a button, a design feature we especially liked.

You also get access to Cobra’s cutting-edge iRadar community/app, which is a crowd-sourced database of known speed traps and red light cameras based on your GPS location. This can all be controlled via the iRadar app, another excellent feature. Unfortunately, the Cobra iRAD 0180003-1 doesn’t feature 360-degree protection, but this was a minimal downside when compared to the long-range detection and iRadar network. The iRAD suffers from some false positives in heavy traffic, but its truly exceptional anti-falling circuitry prevents almost 100% of all false alerts that typically come from traffic monitoring systems and other in-vehicle tech. If you want a cutting-edge Cobra radar detector with long-range detection, the Cobra iRAD 0180003-1 is definitely one of the best options. You may also want to read about the best radar gun.

The stand-out feature of this radar detector is its stunning OLED display. While simple, this display is crisp and clear in any lighting, making it so much easier to read on or off the road.

You’ll also get voice alerts and a user-friendly design with only four total buttons, plus a volume control wheel. The buttons are quick to respond to your touch, a feature which can be hard to find in radar detectors today.

Another stand-out feature here is the RAD 450’s unique IVT filter system, which aims to eliminate false positives.

On top of covering 14 bands of signal, the Cobra SPX 900 also offers complete, 360-degree protection, meaning you’ll pick up signals coming from behind or around you instead of just in front of you. This is an incredibly helpful feature, especially in city environments. You also get compatibility with the iRadar community features and GPS support, but the unit itself lacks Bluetooth, so you won’t be able to use it in conjunction with your smartphone.

How We Choose the Best Cobra Radar Detector

When it comes to selecting the top radar detector from Cobra, having the ability to do hands on testing of different models and brands is a great help. And it’s certainly important to keep an eye on the latest models, as the technology behind radar detectors – whether they’re from Cobra or other manufacturers – continues to evolve. One example is the instant-on technology you’ll find in many of our top picks. It responds instantly when detecting an active radar, which is something other units may struggle to do.

A top Cobra radar detector needs to appeal to a wide variety of users, so we sought out a model with a mid-range price point. Certainly, some users will need more power and features so they’ll want to spend more, and we’ve looked closely at those Cobra units too. But detectors with a middle-of-the-road price work great for many different users, giving them plenty of appeal, especially to those who are new to Cobra or to radar detectors in general.

Why You Should Buy a New Cobra Radar Detector

As mentioned earlier, the technology upgrades in modern Cobra radar detecting units are impressive, making a new unit well worth exploring for the driver who tends to have a lead foot (like me). For example, the Cobra devices on our list do a better job than their predecessors of sorting false K-band alarms from the real radar traps. At the same time, the detector has to be fast to respond, giving you plenty of time to avoid a radar trap. Our top pick, the

A modern Cobra model will be able to use GPS technology to mark locations where false positives occur, eliminating those alarms. And the latest software included in modern radar detectors gives the unit a strong success rate in identifying and limiting false alarms overall.

Perhaps the best new technology found in today’s detectors is the ability of the unit to communicate with smartphone apps to find locations of radar traps, mounted speed cameras, and red light cameras. In testing radar detectors during city driving, having the latest information available is invaluable in giving you a higher success rate when it comes to avoiding tickets from radar-happy cops.

What to Look for in the Best Cobra Radar Detector

Types of Alerts: Radar detectors use different methods of providing alerts, including voice, visual, and alarms. Pick a unit that has the type of alerts that you primarily want to use; some people prefer a voice alert to an alarm, for example. And many Cobra units allow you to use more than one type of alert, which can be helpful if you have multiple drivers using the same detector and each person prefers a different type of alert.

Smartphone Connectivity: The latest feature for radar detectors is Bluetooth connectivity, which allows the detector to connect with a smartphone to make use of realtime information. You will need to have some knowledge of how to set up Cobra radar detector and a smartphone through Bluetooth to make this handy feature work, but it’s well worth the time.

Mistakes to Avoid

Know Your Local Laws: Radar detectors are legal in most states, but some still have laws against radar jammers, against windshield mounted radar detectors, and against using radar detectors in commercial vehicles. Before you purchase and install a detector, understand the laws in the states where you plan to drive the most often.

Don’t Leave the Unit in Plain Sight: Those looking to steal something will gladly grab your radar detector from a parked car. Most units are designed to be removed from the mounting bracket when they’re not in use, so make sure you select one of those designs if you’re concerned about thieves.
